Under complex working conditions such as sewage treatment plant discharge outlets, enterprise sewage discharge outlets, and urban sewers, the quality and quantity of sewage fluctuate greatly over time. Instantaneous sampling often cannot reflect the true pollution load and emission patterns. Sewage samplers (especially automatic mixed samplers) can continuously, proportionally, or periodically collect representative mixed water samples according to preset programs, providing a fair and scientific basis for environmental supervision and internal management of enterprises.
Sewage samplerThe core values lie in "representativeness" and "automation". It simulates a complete emission cycle and collects mixed samples, allowing the analysis results to more accurately reflect the average concentration and total pollutant amount, far exceeding the value of instantaneous sampling.
1. Mixed sampling, strong data representativeness
Proportional or timed mixed sampling can be performed based on traffic or time parameters. When the flow rate is high, the sampling frequency is high, and when the flow rate is low, the sampling frequency is low, and finally mixed into one sample. This method can accurately reflect the average concentration and total emissions of pollutants during the monitoring period, and is the scientific basis for environmental assessment and pollutant discharge fees.
2. Automated operation, 24-hour unmanned operation
Built in intelligent controller and refrigeration system, with pre-set sampling programs (such as 24 hours, 72 hours, or even longer), achieving 24/7 unmanned automatic sampling. Meanwhile, the low-temperature refrigeration function (usually 4 ℃) can effectively inhibit the activity of microorganisms in water samples, prevent sample deterioration during storage, and ensure the accuracy of subsequent analysis results.
3. Strong self-cleaning and anti clogging ability
The composition of sewage is complex, containing a large amount of suspended solids, oils, and other easily clogging substances. High quality sewage samplers are equipped with automatic blowback or flushing functions, which clean the sampling tube and pump body before and after each sampling to effectively prevent blockage and cross contamination, ensuring long-term reliability.
4. Durable and sturdy, adaptable to harsh environments
The shell usually adopts waterproof and dustproof design, which can adapt to harsh environments such as outdoor and underground. The pump tube and flow system are made of corrosion-resistant and wear-resistant materials, which are sufficient to cope with the corrosiveness and abrasiveness of sewage, have a long service life, and low maintenance costs.
The sewage sampler is the forefront sentinel of environmental supervision and sewage treatment. It automatically obtains highly representative sewage samples in a fair and scientific manner, providing data support for pollution source monitoring, sewage treatment process optimization, and standard discharge. It is a reliable guardian of water environment safety.
